Fixed Costs

Break-Even Quantity

The amount you need to sell to at least break even (make zero profit). The formula (assuming that you can sell all you want at price and with constant marginal cost) is Q = F/(P - MC), where F is fixed costs, P is price, and MC is marginal cost.

Zero profits, or normal profit, occur when a company's total revenues exactly match total costs, leaving no net profit or loss.
